Pyrsly,
Man, that is a fantastic shop.
I love to see pictures of creative clutter. Just like home for me.
I know a guy who paints the floor of his shop gray. He never makes anything!
Your DHL design .pdf is slick.
I see you also understand the advantage of CR2 cells. Rare!

Thank You for good word. CR2s ar full of energy and voltage is just right. shame that I can't find rechargeable. easy replaceable with 4x1/3AA 280-300mA NiMH witch can reach 5.5V fully charged bat lasts only fraction of CR2s. Presented plans can be improved by shortening boom by inch or two, les led in nose but smaller static margin. Main idea was to reduce yaw inertia by moving E/R servos to center section of wing, simplifying pod and shortening pushrods. In addition this layout allows stronger wing (center must be reinforced) and running pushrods on outside of pod. Here is more pictures.

Pyrsly,
New wing looks great!
If you are adding lead with CR2's you may get much greater service with CR123 cells.
They are 6g. heavier than CR2, but have nearly double capacity (1550mA). Here is a link showing same cell in double package (CRP2) for $3.30.http://www.calcellular.com/crp2-dl223.html
Good luck.

Those are all rechargable cells. Most guys that have experience with CR2's would never go back to charging/cycling. Camera batteries are cheap, safer, and always ready.

So why are they safer? Every battery has a fairly flat current output but when the charge is used up you reach the "avalanche" point where the voltage drops quickly. I face the "avalanche" with some slight risk about every 22 flying hours. With typical small packs you may face avalanche every 1.5~2 flying hours. And that is if your charger has cut off at the right peak and the cells are really fully charged.

The CR123's are predicted to nearly double that time, but I'm still evaluating that.
